ALFRED O. EINSTEIN, OF ST. LOUIS, MISSOURI.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 783,251, dated February 21, 1905. Application filed August 16, 1904:. Serial No. 220,921.

1'0 all whom it may concern.-

.Be it known that I, ALFRED O. EINSTEIN, a citizen of the United States, residing in the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a full, clear, and exact description reference being had to the accompanying drawings, forming a part of this application.

The object of my invention is to produce a carbid-feed device for acetylene-gas generators whereby an intermittent feed is assured.

My invention consists, broadly, in a revoluble inclined discharge-plate disposed wholly out of a horizontal plane, means for feeding the material to the plate to one side of the plates greatest elevation only, and means for rotating the plate in a direction to cause the material to be carried to the greatest elevation of the plate and discharge -on the other side of the elevation, the material being thus carried in the arc of a circle before being discharged.

Figure l is a view, partly in vertical section and partly in elevation, of the upper portions of the acetylene-gas generator or tank and gasometer-bell with my feed mechanism located therein. Fig. 2 is a vertical section of the feeding lmechanism detached and partly broken away. Fig. 3 is a horizontal section on the line 3 3, Fig. 2. Fig. 4 is a detail view of the iced-mechanism gear. tail perspective view of a section of a modification of the discharge-plate.

1 designates a portion of the gasometertank that is surmounted by two or more uprights 2, only one of which is illustrated.

3 is a gasometer-bell that carries guidebrackets 4, that have sliding engagement with the uprights 2.

5 is a generator-tank, in the upper end of which is positioned a carbid-holder 6, closed at its upper end and open at its lower end.

7 is a hopper connecting with the open lower end of the carbid-holder, said hopper being integral with a cap 8, having a depending annular flange 9, from the lower end of which Fig. 5 is a dean annular lug 10 extends at right angles. This cap is provided with a bearing-seat 11, to be hereinafter referred to.

12 is a casting of the same general construction as the cap 8 and provided with a chute 13. It will be noted that the upper end of the hopper 7 and lower end of the chute 13 are in a horizontal plane, while the general plane of the chamber 14, formed by the cap 8 and casting 12, is on a plane inclined to the horizontal. The casting 12 is provided with a boss 15, having a journal-bearing therein in line with the bearing 11, formed on the cap.

16 is a trip-lever, the free end of which extends into the path of travel of one of the gasometer-bell brackets 1, as clearly shown in Fig. 1. This trip-lever is furnished with a counterbalance-weight 18, which is loose on the shaft '19, said shaft being mounted in a bearing 20, supported by the wall of the generator-tank. The trip-lever has an engagement with the shaft 19 through the medium of a ratchet-and-pawl device 21. The shaft 19 extends into the interior of the generatortank, and its inner end is rotatably seated in a bearing 22, which is supported by a crossbar 23, supported on uprights 24. Fixed to the shaft 19 is a beveled gear-wheel 25.

26 is a shaft journaled in the bearings 15 and 11, the lower end of which is stepped in a bracket 27. Fixed to the shaft 26 is a beveled pinion 28, that meshes with the beveled gear-wheel 25, so that motion imparted to the shaft 16 is transmitted to the shaft 26, whereby the inclined plate 29 is keyed to the shaft 26 and mounted within the chamber 1 1, said plate having upon its upper face a cupshaped projection 30, concentric with the shaft 26. I

31 is a spiral chute, the upper end of which is bolted to the discharge end of the hopper 7, said spiral chute extending from the hopper 7 to a point to one side of the shaft 26 on the inclined plate 29, the bottom of the discharge end of the spiral chute being positioned relative to the surface of the inclined plate, sothat there is just snflicient space between the two to permit of the revolution of the inclined plate without friction between it and the discharge end of the spiral chute. It will be seen from Fig. 2 that the carbid is fed from thespiral chute onto the inclined plate 29 to one side of the platess greatest elevation.

32 is a wiper having a suitable hinge connection 38 with the under face of the spiral chute, said wiper being positioned on the side of the shaft 26, opposite the outlet or discharge end of the spiral hopper, as clearly shown in Fig. 3.

The chamber 14 is of course of greater diameter within the inclined plate 29, as will be seen from Figs. 2 and 3, whereby a space 34 is provided between the periphery of the inclined plate 29 and the chamber, said space being at the lowermost point of the chamber, as more clearly shown in Fig. 2.

When the bell of the gasometer associated with and forming a part of the gas-generator descends, due to the consumption of the gas in the gasometer, the bracket 17 strikes against the free end of the trip-lever 16, thereby forcing the trip-lever downward and rotating the shaft 19 and its beveled gear-wheel 25. Through the medium of the gear-wheel 25 and the pinion 28 the-shaft 26 is rotated, thereby rotating the discharging-plate 29-, whereby the carbid which has been deposited on said plate from the carbid-holder by means of the spiral chute is carried around on said plate 29 and finally discharged therefrom into the space 3 1, whereupon it falls into the generating-chamber. Should any carbid have a tendency to adhere to the discharge-plate 29, it is scraped therefrom by means of the wiper 32. 35 is a guard. As the carbid moves downwardly through the spiral chute and falls upon the discharge-plate 29 it is prevented from falling from the plate by reason of the close proximity of the edge at the mouth of the chute to said discharge-plate. As soon as the supply of gas within the gasometer has been renewed by additional generation of gas due to the discharge of carbid into the generator-tank the gasometer-bell ascends and the counterbalance-Weight 18 returns the trip-lever 16-to its normal position, during which action the carbid banks upon that portion of the discharge-plate immediately under the discharge end of the spiral chute, and a charge of carbid is thus ready to be discharged upon the next action of the feeding mechanism.

Thus it will be seen that by my invention I have provided a revoluble inclined dischargeplate disposed wholly out of ahorizontal plane, means for feeding the material to the plate to one side of the plates'greatest elevation only, and means for rotating the plate in a direction to cause the material to be carried to the greatest elevation of the plate and discharged on the other side of the greatest elevation of the plate, the material being thus carried in the arc of a circle before being discharged.

What I claim, and desire to secure by Letters Patent, is

1. In a feed mechanism for acetylene-gas generators, the combination of a revoluble in clined discharge-plate, of means discharging carbid on said plate to one side of its highest elevation and preventing the discharge of the carbid from said plate until the carbid has reached a point on the other side of the highest elevation of the plate.

2. In a feed mechanism for acetylene-gas generators, the combination with a revoluble inclined discharge-plate of a feed-spout arranged to deliver carbid onto the dischargeplate the delivery end of which is positioned relatively to the discharge-plate to prevent the discharge of the carbid until after it has traveled to the highest point of the dischargeplate.

3. In a feed mechanism for acetylene-gas generators, the combination of a revoluble inclined discharge-plate disposed wholly out of a horizontal plane, means for feeding the material to the plate to one side of the plates greatest elevation only and means for rotating the plate in a direction to cause the material to be carried to the greatest elevation of the plate and discharged on the other side of the elevation.

4:. In a feed mechanism for acetylene-gas generators, the combination of a revoluble inclined discharge-plate disposed wholly out of a horizontal plane, means for feeding the material to the plate to one side of the plates greatest elevation only, means for rotating the plate in a direction to cause the material to be carried to the greatest elevation of the plate and discharged on the other side of the greatest elevation and a protuberance extending upwardly from the central portion of the plate.

5. In a feed mechanism for acetylene-gas generators, the combination of a revoluble inclined discharge-plate disposed wholly out of a horizontal plane, a feed chute disposed above the plate eccentric to the plates axis and having its discharge completely to one side of the greatest elevation of the plate, and means for rotating the plate in a direction to cause the material to be carried to the greatest elevation of the plate and discharge on the other side of the greatest elevation.

6. In a feed mechanism for acetylene-gas generators, a revoluble inclined dischargeplate, means for rotating said plate, a feedspout having its discharge end positioned above said plate eccentric to the plates axis and arranged to deliver carbid onto the plate at a point below the highest point of the plate, whereby upward movement of the oarbid on the plate is necessitated previous to its doWn- Ward movement and discharge from the plate, and a Wiper sun-mounting said plate at the lower portion thereof, substantially as set forth.

The foregoing specification signed this 15th day-of July, 1904.
